Abalistes is a small genus of marine ray-finned fishes belonging to the family Balistidae, the triggerfishes. These triggerfishes are found in the Indo-Pacific and eastern Atlantic. This genus contains two recognised species.

Taxonomy

Abalistes was first proposed as a genus in 1906 by the American ichthyologists David Starr Jordan and Alvin Seale with Leiurus macrophthalmus the type species. L. macropthalmus was originally described by William John Swainson with Leiurus being proposed as a subgenus of Capriscus, i.e. Balistes , but he used the same name in the same book for a subgenus of the stickleback genus Gasterosteus , meaning that it was unavailable for the triggerfish. [2] This genus belongs to the family Balistidae which is classified within the suborder Balistoidei. [3]

Etymology

Abalistes prefixes a-, meaning "not", with Balistes, the genus that A. stellaris, a synonym of A. stellatus, was considered to belong to. [4]

Species

There are currently two recognised species in this genus: [5]

Characteristics

Abalistes triggerfishes are distinguished from the othere triggerfish genera by the morphology of the caudal peduncle which is wider than it is deep, i.e. depressed rather than compressed. They have a terminal mouth with uneven notched teeth. [7] The largest of the two species in the genus is the starry triggerfish (A. stellatus) which has a maximum published total length of 60 cm (24 in), A. filamentosus is much smaller with a maximum published standard length of 32.5 cm (12.8 in). [8]

Distribution

Abalistes triggerfishes are found in the Indo-Pacific from the Red Sea and the eastern coast of Africa east through the Indian Ocean and into the Pacific Ocean north to southern Japan, south to Australia and east to Fiji. [9]

Triggerfish are about 40 species of often brightly colored marine rey-finned fishes belonging to the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.
